T 0 all whom it may concern:

Be it known that we, ABRAHAM 'l. Bin:- Lnn, a citizen of the UnitedStates, residing at Kansas City, Jackson county, Missouri, and ISAAC ViBEELER, a citizen of the United States, residing at Kansas City, in thecounty of Vfyandotte and State of Kansas, have invented a new and usefulFloor-Scraper, of which the following is a specification.

This invention relates to lloor scrapers and has for its object toprovide a comparatively simple and inexpensive device of this characterespecially designed for planing and smoothing hard woou lloors and othersurfaces.

A further object of the invention is to provide a scraper including abody portion raving a plurality of cutting blades at one end thereof anda wheel or roller at the other, there being a handle pivotallv mountedon said bod portion and arranged to he swung downwardly in engagementwith the axle of the wheel thereby to elevate the cutting blades whentransporting the scraper from one portion of a room to another.

A further object is to provide an auxiliary head having a cutting edgearranged at right angles to the longitudinal plane of l he scraper fordressing and smoothing the iloor at the base-board.

A further object is to provide an abrading i head also arranged forattachment to the head of the scraper for polishing and dressing thesurface of the ,tloor after the scraping operation.

A still further object of the invention is generally to improve thisclass of devices so as to increase their utility, durability andefficiency.

Further objects and advantages will appear in the following description,it being understood that various changes in form,

proportions and minor details of construction may be resorted to withinthe scope of the appended claims.

In the accompanying drawings forming a part of this specification:Figure 1 is a side elevation of a floor scraper constructed inaccordance with our invention showing in full lines the cutting bladesin engagement 1 with the upper surfaces of the floor and in dotted linesthe head carrying the blades in elevated position. Fig. 2 IS a top planview.

Fig. 3 is a detail bottom plan view. Fig. if is a perspective view ofthe auxiliary cutting head showing the same in position to be attachedto the adjacent end of the scraper. Fig. 5 is a perspective view of theabrading block.

Similar numerals of reference indicate corresponding parts in all of theligures of the drawings.

The improved scraper forming the subject matter of the present inventioncomprises an elongated body portion 5 having one end thereof terminatingin a head (3 and its opposite end provided with a longitudinallydisposed slot 7 in which is mounted for rotation a wheel or roller 5%.The wheel 8 is mounted for rotation on a stationary axle 9, the oppositeends of which are threaded and extended beyond the adjacent longitudinaledges of the body portion for engagement with correspondinglv threadedcaps it). The side walls of the head (3 are inclined or beveled in thedirection of the front of the scraper and secured to the inclined facesof the head is a weighted cap piece or casing l l. The cap piece isprovided with a horizontal extension 12 which bears against the top ofthe head ti, while the inclined walls of said cap are formed wil hanchoring ribs [3 which cngage correspomlinglv shaped grooves or ichannels formed in. the head and serve to prevent accidentaldisplacement of the cap piece. j Secured to the inclined or beveledfaces of r the cap piece are retaining plates 'l-l having l, their lowerends spaced from the adjacent j walls of the ca p piece to form socketsfor the I reception. of detachable cutting bits or blades 15. Theretaining plates H are secured to the inclined walls of the cap piece (3by means of screws or similar fastening devices (3, which. latter causethe lower ends of the retaining plates to frictionally engage the bits l15 and prevent accidental displacement of l said bits during thescraping operation.

Formed in the bottom of the body portion 6 and extending from thejuncture of the inclined walls of the cap 11. to a point near the 1 rearend of the head (5 is a longitudinallydisposed slot 17 for the receptionof the shank 18 of an auxiliary cutting head 1E). The auxl iliarycutting head l.) is designed for scraping and polishing the surface ofthe lloor at l the base-board, said auxiliary cutter being retained inposition on the scraper by means of a bolt which extends throughvertically alined openings 21 formed in the head 6 and cap piece 11,respectively, for engagement with a clamping nut 22, the latter beingarranged to bear against the horizontal exten sion 12 of the cap pieceand thus prevent wear on the head. The abutting ends of the retainingplates 14 are cut away at 23 so as to accommodate the shank 18 of theauxiliary head 19, the latter being provided with a substantially shapedslot 24 for the reception of the nose of the scraper, as shown.

In order to polish and dress the surface of the floor after the scrapingoperation an abrading member 25 is provided, the latter being formed ofa block having one end thereof inclined or beveled to conform to theshape of the head 6 and its lower surface provided with a strip of sandpaper or other abrading material 26. The upper surface of the block 25is provided with a longitudinally disposed shank or rib 27 adapted toenter the slot 17, there being a bolt 28 extending vertically from theshank or rib 27 and adapted to enter the openings 21 for engagement witha clamping nut 29 similar in construction to the clamping nut 22.Pivotally mounted on the body portion in advance of the wheel or roller8 is a yoke or frame 30 preferably formed of sections of gas pipeconnected by elbow joints 31. The yoke or frame 30 is re inforced andstrengthened by a transverse brace 32 also preferably formed of asection of gas pipe and carrying a'i' section 83 which registers with acorresponding '1' section 34 carried by the adjacent end of the frame,said '1' sections being interiorly threaded for engagement with thecorrespondingly threaded end of an operating handle 35. The yoke orframe 30 of the operating handle is so arranged with respect to thewheel 8 that when the free end of the handle is swung clownwardly, theside walls of the frame will bear against the caps 10 and thus elevatethe cut ting blades 15 above the surface of the floor to the dotted lineposition shown in Fig. .1 of the drawings and in which position thescraper may be moved to different portions of the room on the wheel 8without danger of the blades 15 scraping or otherwise mutilating thepolished surface of the floor.

When the device is used for scraping the center of the floor the blades15 are fastened in position on the head of the scraper and the lattermoved over the surface of the floor by pushing the same in a forwarddirection. The auxiliary head 19 is then attached to the head of thescraper and fastened in position by means of the bolt 20 so that thesurface of the floor at the baseboard may be operated upon. After thesurface of the floor has been planed or scraped the abrading block 25 isfastened to the base of the head 6 by means of the bolt 28 and clampingnut 29 and said scraper moved over the surface of the floor, in themanner before described.

Attention is here called to the fact that the cutting blades 15 aredisposed at an angle to each other so as to prevent slipping of thescraper during the planing operation, said cutting blades being soarranged that by simply reversing the body portion the blades will be inconvenient position to be sharpened without the necessity of detachingsaid blades from the head. The particular disposition of the cuttingblades or bits not only prevents side-wise movement or lateral shiftingof the scraper during the cutting operation but also permits the deviceto run smoothly over the joints in the floor and over cross grain in thetimber.

Having thus described the invention what is claimed is:

1. In a floor finishing tool, a wheel and its axle, a carrier pivotallymounted on the axle, a tool mounted on the free end of the carrier, anda handle pivotally connected to the carrier in advance of the axle, saidaxle being in the path of the handle to serve as a fulcrum.
